Dust is your unnoticeable but reliable ally in protecting your premises

Dust is one of the simplest, yet most reliable, and most importantly, free indicators of unauthorized access.

Methods:
1. Photographic
2. Chemical forensic tools
3. Dust trace detection devices

Note: if a violation of the dust layer is detected, it's possible both to find the fact of access and get more data.

7 ways to spot if someone’ is following you

• Detection of surveillance(tailing) is carried out through a thorough study of the surrounding environment, with an emphasis on repeated encounters watch for repeating patterns with the same persons (vehicles) at various points along the route.
• You should strive to gradually make your perception of your surroundings automatic, automatically registering any suspicious fact: an unfamiliar car in a familiar alley, a person who seems to be reading a newspaper but is not paying any attention to it, a woman in a pay phone booth talking to someone without dialing a number and at the same time carefully watching the entrance opposite.
• Very often, surveillance is conducted not only outside the doors of your building or the entrance to the office where you work, but also through your windows. This means while you're just putting on your coat, a surveillance team is already waiting for you to emerge from the building.
• Detecting surveillance can be either "hard" or "soft." "Hard" surveillance is characterized by regularly tying shoelaces, periodically checking behind you by constantly glancing over your shoulder, use mirrors or reflective surfaces and making sudden contacts with the people conducting the surveillance.
• The "Four-Right-Turns" Method:
  The best advice you can follow is to stay calm and turn right four times consecutively. This will bring you back to your original spot.
